Reginald Rose (December 10, 1920 – April 19, 2002) was an Americanfilm and television writer most widely known for his work in the early years of television drama. Rose's work is marked by its treatment of controversial social and political issues. His realistic approach helped create the slice of life school of television drama, which was particularly influential in the anthology programs of the 1950s.

Rose was married twice, to Barbara Langbart in 1943, with whom he had four children, and to Ellen McLaughlin in 1963, with whom he had two children. He died in 2002 from complications of heart failure.

He sold his first teleplay, Bus to Nowhere, in 1950 to the live CBS dramatic anthology program Studio One, for which he wrote Twelve Angry Men four years later. This latter drama, set entirely in a room where a jury is deliberating the fate of a teenage boy accused of murder, was inspired by Rose's service on just such a trial.The play was later made into a black-and-white movie.

The Internet Movie Database quotes Rose's memories of this experience: "It was such an impressive, solemn setting in a great big wood-paneled courtroom, with a silver-haired judge, it knocked me out. I was overwhelmed. I was on a jury for a manslaughter case, and we got into this terrific, furious, eight-hour argument in the jury room. I was writing one-hour dramas for Studio One then, and I thought, wow, what a setting for a drama."[1]

Rose received an Emmy for his teleplay and an Oscar nomination for its 1957 feature-length film adaptation. Rose wrote for all three of the major broadcast networks of the 1950-80 period. He created and wrote for The Defenders in 1961, a weekly courtroom drama spun off from one of Rose's episodes of Studio One; The Defenders would go on to win two Emmy awards for dramatic writing.
